In a security guide published Wednesday, Apple recommends that children under the age of 13 do not use Face ID due to the probability of a false match being significantly higher for young children. The company said this was because “their distinct facial features may not have fully developed”.
With Face ID, Apple has implemented a secondary system that exclusively looks out for attempts to fool the technology. Both the authentication and spoofing defence are based on machine learning, but while the former is trained to identify individuals from their faces, the latter is used to look for telltale signs of cheating.
